Sectoral shares of acidifying pollutants (SO2, NOx, NH3; energy and non-energy components) of total emissions, EEA-32. Values within the segments indicate the level of emissions (kt) emitted from each sector.
The emissions of acidifying pollutants (sulphur dioxide SO2, nitrogen oxides NOx and ammonia NH3) are each weighted by an acid equivalency factor prior to aggregation to represent their respective acidification potentials. The acid equivalency factors are given by: w(SO2) = 2/64 acid eq/g = 31.25 acid eq/kg, w(NOx) = 1/46 acid eq/g = 21.74 acid eq/kg and w(NH3) = 1/17 acid eq/g = 58.82 acid eq/kg.
